Against the abusive invocation of self-defence against terrorism

A collective open letter signed by a great number of professors of international law and researchers entitled « A plea against the abusive invocation of self-defence as a response to terrorism » is circulating on the web for a few weeks.

Among the signatories, of which there are more than 230 professors and 50 assistants/researchers (see the list available here at July 29, regularly updated by the Centre de Droit International de l´Université Libre de Bruxelles, ULB) , we find distinguished members of international law community as well a younger researchers and assistants. The objective of this collective initiative is to challenge the invocation of the legal argument of self-defence by several States in the context of the so called “war” against ISIL or ISIS.

As well known, the United Nations Charter is extremely clear on the unique exception to the prohibition of the use of force since 1945: self-defence (and military operations authorized by Security Council under Chapter VII of the Charter). However, since 9/11, interpretations made by United States and its allies have tried to legally support unilateral military operations in the territory of a State without previous consent of its authorities.

In a recent note published on the website of the prestigious European Journal of International Law (EJIL), we read that: “Particularly since 9/11, several States have supported a broad reading of the right to use force in self-defence, as allowing them to intervene militarily against terrorists whenever and wherever they may be. A consequence of that conception is that any State could be targeted irrespective of whether that State has ‘sent’ the irregular (in this case terrorist) group to carry out a military action or has been ‘substantially involved’ in such an action” (Note 1).

The use of force in self-defence must be exercised in conformity with the conditions laid down in international law, and particularly the UN Charter. On this very particular last point, it must be recalled that France presented to the Security Council a quite surprising draft resolution after Paris attacks of November 13, 2015 (see full text of the « blue version » circulated among delegations) avoiding any reference to the Charter in its operative paragraphs: it is possibly a great “première” of French diplomacy at the United Nations (Note 2).

« Thus, numerous military interventions have been conducted in the name of self-defence, including against Al Qaeda, ISIS or affiliated groups. While some have downplayed these precedents on account of their exceptional nature, there is a serious risk of self-defence becoming an alibi, used systematically to justify the unilateral launching of military operations around the world».

«Without opposing the use of force against terrorist groups as a matter of principle — particularly in the current context of the fight against ISIS — we, international law professors and scholars, consider this invocation of self-defence to be problematic. In fact, international law provides for a range of measures to fight terrorism. Priority should be given to these measures before invoking self-defence ».

For the signatories of this collective letter,

« …. we consider that terrorism raises above all the challenge of prosecution and trial of individuals who commit acts of terrorism. A variety of legal tools are available in this respect. They relate first and foremost to police and judicial cooperation (chiefly through agencies such as INTERPOL or EUROPOL), aiming both at punishing those responsible for the crimes committed and preventing future occurrence of such crimes. Although there is certainly room for improvement, this cooperation has often proved effective in dismantling networks, thwarting attacks, and arresting the perpetrators of such attacks. By embracing from the outset the « war against terrorism » and « self-defence » paradigms and declaring a state of emergency, there is a serious risk of trivializing, neglecting, or ignoring ordinary peacetime legal processes”.

It must be noted that this document is open for signature by international law scholars and researchers around the world until next September 1st. The text recalls a certain number of very clear rules that diplomats and judges at the International Court of Justice (ICJ) in The Hague, and diplomats in New York know better than anyone, despite the ambiguous interpretations made by some of their colleagues at the Security Council, in particular since the beginning of airstrikes in Syria, without the consent of its authorities (Note 3).

This document also refers that:

« …, the maintenance of international peace and security rests first and foremost with the Security Council. The Council has qualified international terrorism as a threat to the peace on numerous occasions. Therefore, aside from cases of emergency leaving no time to seize the UN, it must remain the Security Council’s primary responsibility to decide, coordinate and supervise acts of collective security».

« Confining the task of the Council to adopting ambiguous resolutions of an essentially diplomatic nature, as was the case with the passing of resolution 2249 (2015) relating to the fight against ISIS, is an unfortunate practice. Instead, the role of the Council must be enhanced in keeping with the letter and spirit of the Charter, thereby ensuring a multilateral approach to security /…/ However, the mere fact that, despite its efforts, a State is unable to put an end to terrorist activities on its territory is insufficient to justify bombing that State’s territory without its consent».

«Such an argument finds no support either in existing legal instruments or in the case law of the International Court of Justice. Accepting this argument entails a risk of grave abuse in that military action may henceforth be conducted against the will of a great number of States under the sole pretext that, in the intervening State’s view, they were not sufficiently effective in fighting terrorism».

It must be noted that in February 2016, Canada new authorities decided to cease airstrikes in Syria and Iraq. We read on this official note produced by Canadian Armed Forces (CAF) that: “ In accordance with Government of Canada direction, the Canadian Armed Forces (CAF) ceased airstrike operations in Iraq and Syria on 15 February 2016. From their first sortie on 30 October 2014 to 15 February 2016, the CF-188 Hornets conducted 1378 sorties resulting in 251 airstrikes (246 in Iraq and 5 in Syria), expended 606 munitions and achieved the following effects: 267 ISIL fighting positions, 102 ISIL equipment and vehicles, and, 30 ISIL Improvised Explosive Device (IED) factories and ISIL storage facilities”.

In 2015, a Canadian scholar concluded an extremely interesting article on airstrikes in Syria and Iraq in the following terms: “However, there is a further legal hurdle for Canada to overcome. Unless Canada can attribute ISIS´ attacks in Iraq to Syria, then the question becomes whether Canada may lawfully target ISIS, as a nonstate actor in Syria’s sovereign territory, using the ‘unwilling or unable’ doctrine to prevent ISIS’extraterritoriality attacks against Iraq. This justification moves significantly away from the Nicaragua, Congo and Israeli Wall cases’ requirement for attribution. There appears to be a lack of consensus on whether opinion juris and state practice have accepted the “unwilling or unable” doctrine as customary international law. There is no escaping the conclusion that Canada’s air strikes on Syria are on shaky, or at least shifting, legal ground ” (Note 4).

Graphic on airstrikes in Syria launched by United States (blue color) and “Arab allies and Canada” (in red color) from December 2014 to August 2015, published in this report of Airwars.org entitled: “First year of Coalition airstrikes helped stall Islamic State – but at a cost “.

Concerning airstrikes in Syria and Iraq by coalition member States (see for example the detailed report for July 2106 prepared by the NGO Airwars.org), the systematic registry of every single airstrike give a more complete idea on how tasks are shared inside the coalition: illustrative charts realized by Airwars.org clarify the fact that bombs exploding in those two States are mainly dropped from United States aircrafts .

In particular, a careful reading of Chart 9 of the before mentioned link (see the column corresponding to July 2016) shows that at July 25st, in Syria 4414 airstrikes from United States have took place in July 2016, while 249 were realized by other coalition members (officially 10 States are part to the coalition in Syria, to which Canada cannot be included anymore concerning airstrikes (nor in Syria, nor in Iraq), and that since February 2016).

With regard to civilian harm in Syria caused by airstrikes, a recent report of June 2016 states that: ”This raises concerns that important, corroborating information was either never identified or discounted with little justification, a concern confirmed by a comparison to an investigation by Airwars into one of the strikes involved, which demonstrates that open source data was overlooked. As a result of these apparent shortcomings, it is highly likely that there is a significant amount of information regarding civilian harm and its strategic impact that the United States simply does not know”(p. 55).

The signatories of this collective call, whose number increase from day to day, including scholars from different continents and age, conclude reaffirming that:

« The international legal order may not be reduced to an interventionist logic similar to that prevailing before the adoption of the United Nations Charter. The purpose of the Charter was to substitute a multilateral system grounded in cooperation and the enhanced role of law and institutions for unilateral military action. It would be tragic if, acting on emotion in the face of terrorism (understandable as this emotion may be), that purpose were lost ».
